Environment and Evolution of human being Research Paper

Environment and Evolution of human being - Research Paper Example nce has been collected through considerations of facts like fossils of the early human skull and concurrent bone structure that indicated the presence of the differences in the structure of human with respect to respective age period in the past. Such differences were notable in the human skull morphology, for instance, in some human species like Lucy. The stand has been further supported by Adrienne Zihlmans article regarding "paleosols" that hugely back up the relationship between environment and human evolution (Penna, 2010). According to (Haviland, 2007), the current theory and entailed elaborations on the evolution of man attains its backing from a set of independently notable observations well placed in the fields of anthropology, molecular biology and other sectors like paleontology. All the three segments outline or exhibit life originating from a common point of ancestor and then branching into various categories under a gradual and progressive genetic changes spanning millions of years in a "tree of life" that is hugely influenced by environmental variations. Evolution of man similar to other animals in the ecosystem has been impacted by the environment that has consecutively acted in the formats of three main principles. The first principle is through microevolution that refers to the presence or the occurrence and establishment of build-up of mutations acting on the genetic sequence of an organism. The environment created huge impacts on established of the new establishment of build-up of mutati ons acting on the genetic sequence from the historic ancestor of man. Though the change can equally occur naturally. Several environmental effects have been linked to the microevolution of the mankind especially those originating from different geographical regions. The main environmental variations includes existent chemicals and varied earth radiations notable in various parts of the earth. Environmental radiations is believed to contribute to the difference
